Polyethylene Glycol (PEG) is a synthetic, water-soluble polymer composed of repeating ethylene oxide units (HO(CH₂CH₂O)ₙH), available in varying molecular weights (liquids to solids). Renowned for biocompatibility, low toxicity, and solubility in water/organic solvents, PEG is widely used in pharmaceuticals (drug delivery, coatings), biotechnology (protein purification, nucleic acid delivery), and industrial applications (cosmetics, food additives). While generally safe, rare hypersensitivity risks exist. Its adaptability and safety make it indispensable across scientific and commercial fields.
